fix: sync Cursor suggest-compact.js with corrected hooks version

The .cursor copy had diverged from scripts/hooks/suggest-compact.js:
- Fixed interval calculation: count % 25 → (count - threshold) % 25
  so suggestions fire relative to the configured threshold
- Added upper bound clamp (<=1000000) to prevent counter corruption
  from large values converting to scientific notation strings
- Removed unreliable String(process.ppid) fallback for session ID
